Application filed Ju1y20, 1922. ,SrialNo. 576,307.

To all whom it may conceive: Be it known thatl l3 Jam RALEIGH, a citizen of'the United States, residing at lV-ashington, District of Columbia, have invented. a new and useful Phonograph-Rem rd Replayer, ofwlnclrthe following we specification.

My invention relates to improvements for a phonograph record replayer in which the rotation power of the record is harnessed to operate the replayer.v v

One ofthe objects of the above invention is toprovide a device that will automatically return the needle or stylus at the starting point of the record after the record has been once played. 7

A i'urther object ofthis invention is to provide a device by which a record for any talking machine now in general use may be played an unlimited number of tunes withoutcare or attention on the part of the operator.

One of theobjects of the present invention is to provide a simple and practical phonograph} record replayer ofthe above character having relatively .few parts which may be inexpensively manufactured and'assem- A further object is to provide a'li-ght,-and durable device of the above character for accomplishing the above. y

In. these drawings, wherein similar reference characters denote corresponding parts I Fig. l; is the adjustable type of phonograph record re player;

Fig. 2 is a similar but non-adjustable type of phonograph record replayer;

Fig. 3. is a similar view of a modified form of replayer; I

Fig. 4 is another view showing a still further modification;

sists primarily of two substantially rectangular plates 4 and 5 madev preferably from a light metal such as aluminum or from a fibersubstance. These plates are joined by the thumb screws on holding pins 7 which are placed in the slots 6 as shown.

By means of these thumb screws and slots 1 the coacting plates 45and 5 can be adjusted longitudinally or can be held in positive position at a predetermined point. Cen-;

trally disposed slots 8 and 10 are cut in the inner ends of said plates through which the central stud ofthe turntable projects. The slots 11 and 12 are provided near the outer edge of the members 1 and 5 and adjoining these slots 11 and 12 are the guide ways 13 and Li which carry the needle into replay position. The raised portions '15 prevent the needle from jumping the plate,

Y and guides the same into the playing slots 11 and 12. At any convenient place on one of the plates may be marked a small scale 16 enabling one to obtain an approximate adjustment for the different size records.

Explaining now in detail the operation of hills, replayer device on a record 111 its usual position to be played, the stud of the turntable coming through the openings Sand 10, the stylus or needle is placed as at A and the phonograph started. Due to the weight of the device, as the record rotates causing the needle to follow the helical groove; in the record, the replayer device is slowly rotated. As the needle reaches the position where it has completed playing it will advance from the slot 11, will be guided by theguide way 18, which again due to the rotation of the record is given a quick swirling movement, and carries the needle in the position denoted by B, Figure 1,-in replay position in the slot 12, and the cycle is repeated. This operation can be carried on an unlimited number of times in a like manner and without, aid or operation from one using themachine. I 1

Referring now to'Figure 3, this drawing Shows a modified type of replayer, This is not of the adjustable type but can be made in dilii'erent sizes to suit the record to be played. This modification consists of a single rectangularplate 18 in which the stylus groove 20 is placed,,running for a distance 21 leading to the guide ways 22. The purpose of this addit onal curve 21 1s to enable.

the replayer to operate on records either partly or fully grooved. It is well known that some records are shorter than others and it has been found that replayers now on the market do not provide any means necessary for such abnormally long or short records. I 8 Referring to Figure 4t, :1 further type of replayer is disclosed. Disposed radially about a substantially circular plate are the outwardly extending arms 24:. As seen from the drawing, three of these arms are provided but I do not wish to be limited by any set number 01' such arms and a plurality of arms could be used instead of the three described in the drawing. Referring again to the drawings, slots 25 are provided in each of the arms along which the needle is guided. Angular-1y or circularly disposed from the slot 25 is the slot 26 which as in the modl eation shown in Figure enables records ct any length to be played.

Referring again to Figure 1, the thumb screws '7 may be padded with fabric or felt on t-hir bottom faces thereby acting as a silencer and also by friction gripping the record more closely. It might be well to note here that the guide ways ll, 19, 22 and are not limited to any particular form but may be in the shape of a groove, boss, a vertical boss or a circular boss.

it will thus be seen that the present invention provides a simple and practical phonograph record replayer and one that will be ellicient and practical in operation, and while I have described my invention in corn nection with certain preferred embodiments, I wish it understood that I do not limit my invention to the embodiments shown and described, GKCQPt in so far as specific limitations may appear in the appended claims.

I claim:

1. An adjustable record replayer comprising two plates having longitudinal slots therein, said plates being adapted to slide one on the other, and guide ways adapted to lead a stylus on a predetermined path.

2. An adjustable record replayer comprising two members harin g slots therein per-mitting longitudinal adjustment of said members, and there being a longitudinal stylus slot in each of said members, and raised portions on each of said members adapted to guide the stylus from the slot on one member to the slot in the other member.

3. An adjustable record replaycr for a rotating record comprising two plates, means permitting a longitudinal adjustment of said plates, there being a stylus guide slot in each of said plates, and guide ways adapted to lead the stylus from the slot in one plate to the replay slot in the other plate.

4t. A record replayer for talking machine records of all lengths comprising a substantially rectangular plate having stylus slots therein, guide ways associated with said plate, a portion of each of said stylus slots being disposed angularly of the remaining portion oi each slot.

5. A record replayer comprising a substantially rectangular plate having two stylus slots disposed at substantially diagonally opposite corners of said plate, guide bosses on said plate forming a guide for the stylus from the end of one oi said slots to the beginning of other oi? said slots, said slots being angular-1y disposed for a portion of their lengths thereby permitting a record of any length to be replayed.

G. In a phonograph record replayer, a plate having openings therein to provide a plurality of elongated abutinents to engage the needle of the phonograph as the record is being played, and a passageway for the needle connecting the inner end of each abutment with the outer end of another abutment.

7. A pair of complementary plates each having a plurality of slots therein, means for securing together said plates in desired adjusted position with said slots in registry, and a guideway on each plate for directing a needle from one end of a slot to the opposite end of another slot.
